A meter collar is an adapter that may be inserted between a meter socket box and the meter. The meter collar may include a housing that is provided with first contacts to facilitate a mechanical and electrical connection with utility-side contacts of the meter socket box and second contacts to facilitate a mechanical and electrical connection with customer-side contacts of the meter socket box.

The present disclosure relates to a device for carrying a chip, and a device and a method for testing a chip. The device for carrying a chip is configured to fasten chips of different sizes, and includes a support box and a plurality of first elastic snap rings. The support box is configured to carry a chip. A first connection terminal of the first elastic snap ring is provided on a first inner side wall of the support box, a second connection terminal of the first elastic snap ring is suspended, and is configured to be in contact with the chip and provide a pressure in a first direction for the chip because an elastic body of the first elastic snap ring is in an elastically compressed state.

An assembly or adapter configured to provide a supply-side interconnect of electrical power to a distribution board. The adapter may be incorporated internal or external to the distribution board, by occupying the space of one or more circuit breakers, inserting an adapter into a meter termination socket, or the like. The adapter includes terminals provided to route the conductors from the utility to a breakout panel (or subpanel) for adding power devices as a supply side interconnect, and back to a regular route that may go through the meter and/or the main circuit breaker, and on to the loads. A switching component may provide an inline configuration that configures the conductors for backup function, and a parallel configuration that is a parallel interconnecting route when utility service is available.

A biosignal measurement system comprises an adapter for a biosignal measurement device, and an external support structure separate from the adapter. The adapter comprises tool-less connectors, which are repeatedly connectable to and disconnectable from their counter connectors of the external support structure, and a device connector, which has an electrical connection with the tool-less connectors and which has a connection with the biosignal measurement device that the adapter carries. The external support structure comprises an electrode support structure with electrodes and tool-less counter connectors, the electrodes and the tool-less counter connectors having an electrical connection therebetween. The electrodes form an electrical contact with skin for receiving the biosignal. The counter connectors are in electrical contact with the connectors of the adapter for transferring the biosignal to the biosignal measurement device through the adapter.
